Ana is a dedicated Skee Ball player who always rolls for the 50-point slot. The probability distribution of Ana's score X on a randomly selected roll of the ball is shown here. The mean of this probability distribution is 23.8. Score Probability 10 20 0.32 0.27 30 0.19 40 0.15 50 0.07 What is the standard deviation of X? Interpret this value. x = 12.632. The score of a randomly selected Skee Ball roll will typically vary from the mean (23.8) by about 12.632. ox= 159.56. The score of a randomly selected Skee Ball roll will typically vary from the mean (23.8) by about 159.56. σχ = 159.56. The score of a randomly selected Skee Ball roll will vary from the mean (23.8) by 159.56. The standard deviation cannot be calculated in this situation because we do not have a list of randomly selected Skee ball point values. Oox = 12.632. The score of a randomly selected Skee Ball roll will vary from the mean (23.8) by 12.632.
